According to water jet machine manufacturers, waterjet cutting is a qualified engineering method for cutting. This method of cutting is powerful enough to cut through an object by utilizing the energy that comes from a high density, high speed, and pressurized water.
The water used in this cutting technology is pressurized. It is given a power of 392 MPa, which is estimated to have 4,000 atmospheres. After reaching this enormous amount of pressure, the water is projected to your target object from a small-bore nozzle which is about Φ0.1 mm.
The moment that the ultra-high pressure pump pressurized the water, it would have reached a speed that is 2 -3 times the speed of sound. Once this level is reached, it will produce a water jet force so strong, it easily becomes a destructive force.
There are varied applications for it. We are familiar with some of them. Like cutting roof materials, or for cutting out and shaping automobile bumpers or dashboards. You can also use water jet cutter in demolishing concrete structures. It has also practically used in cutting aircraft fuselages.
For many years now, the waterjet machine has become a ubiquitous piece of equipment in the automotive industry. This cutting edge technology is most in-demand in this sector of the manufacturing business because you can integrate it with robotic systems.
The absence of abrasive particles in the cutting process or water-only cutting is the method of choice when it comes to the production of interior carpets, head linings, and insulation. The underlying reason for this is that water jet cutting produces minimal to no waste material. Plus the fact that it does not come messy, too. Below are some applications for water jet cutter.
Military and Defence
Armor plating, shaping, bullet-proof composites, and glass are among the typical applications of water jet cutting technology in the military and defense industry. Since water jet cutting is a qualified cold cutting process, it is regarded as among the few processes that are suitable for use in cutting those materials mentioned above sans causing changes in their molecular structure or badly impacting its structural strength. Truth be told here but the military and defense industry is relying solely on waterjet technology.
Waterjet technology can virtually cut almost any imaginable material there is. This would include brass, copper, tempered steel, bisalloy, titanium and a manifold of other exotic, maybe unheard of, metals.
Abrasive water jet cutting can cut through a material that is up to 200mm thick without having to produce a heat-affected zone. It also allows for precise cutting of intricate parts without having to compromise the high tolerance range.
Outstanding Water Jet Cutting Features
The following outstanding features of a waterjet machine makes this technology the method of choice in various industries, other than what was stated above.
- The absence of heat production
The use of water jet cutting machine for your materials processing, cutting, or fabricating needs means you are adapting to the use of a non-contact way of processing it. There are no drills to use, and you will have no need for any kind of tools that will touch your material or object. Therefore, the production of heat is a thing of the past. So, you don’t have to worry about eventual alteration procedures to the object and it will not likely have any change in color, too.
2. Allows for Cutting of Various Materials
What amazes most people about waterjet technology is the fact that, contrary to the general impression of many, the process requires the use of a small amount of water only. Much like the laser method of cutting, right this very moment there are no known limits to what you can handle with waterjet cutting machine.
3. Allows for Cutting of Objects with Intricate Shape and Design
If you happen to have a fabricating project that requires you to execute intricate cuts to your material, perhaps you can just give it a waterjet cut instead. Seamless cutting for 3-dimensional bodies is also possible as well as 2-dimensional shapes.
This method of material cutting is water-based, therefore it makes sense that it will not produce dust or any harmful byproducts. In that case, this method of cutting will not put your workers in harm’s way and it will not have any damaging impact on the environment.
This method of cutting materials can be carried out only with the use of water. In time-sensitive projects, the use of sand particles or abrasive materials (granite particles) may be considered to further accelerate the cutting process time. Still, it remains environment-friendly.
